Abstract
The utility model discloses a gear rack diverter, which comprises a gear rack limiting device (2), a diverter casing body (4). An elastic device (5) is arranged at the end of the of the gear rack limiting device (2) neat to the diverter casing body (4). Because the utility model adopts the above structure, during the driving process, when the driver turns the steering wheel to the limiting position, the hands can feel heavy, to enable the driver to know that the steering limiting position is reached; as for the diverter, the rigid impact of the gear rack and the casing body is changed into a flexible impact, and the service life of the diverter is enhanced; when the limiting position is turned to, the steering wheel can be automatically rebounded to a small stroke form the limiting position, avoiding the state that the steering oil pump is at the maximum working pressure, and enhancing the service life of the steering oil pump.
Description
Technical field
The utility model relates to auto parts and components, especially relates to a kind of rack and pinion steering gear.
Background technique
Present common rack and pinion steering gear, comprise commutator drag link 1, tooth bar limit stoper 2, steering gear rack 3, steering gear housing 4, commutator drag link 1 links to each other with wheel, steering gear housing 4 links to each other with vehicle body, and tooth bar limit stoper 2 and the steering gear rack 3 that is attached thereto are between commutator drag link 1 and steering gear housing 4.When steering gear rack 3 moved to the steering lock position, the limiting stopper and the steering gear housing of tooth bar end were collided, and this moment, driver's steering wheel was got to limit position, can't be rotated further.If the driver can feel a kind of unexpected bump with fast speed steering wheel rotation very when getting to limit position, this is to be formed by the impact between tooth bar limiting stopper and the steering gear housing, causes the life-span of rack and pinion steering gear shorter; If the driver rests on steering wheel on the limit position for a long time, steerig pump will be in the maximum service pressure state always, reduces the working life of steerig pump.
The model utility content
Technical problem to be solved in the utility model is: a kind of rack and pinion steering gear is provided, and this rack and pinion steering gear can be avoided
For solving described technical problem, the technical solution of the utility model is: a kind of rack and pinion steering gear, comprise the tooth bar limit stoper, and steering gear housing, described tooth bar limit stoper is provided with elastic device near the end of steering gear housing.
Described elastic device is the spring ring affixed with limit stoper.
Described elastic device be with the affixed concentric circle of limit stoper on the uniform spring sheet more than three.
Described elastic device be with the affixed concentric circle of limit stoper on the uniform ball bearing mechanism more than three, described ball bearing mechanism by the cavity of limit stoper end, be positioned over the pressure spring in the cavity, the ball that contacts with pressure spring is formed, the major part of ball is stuck in the described cavity.
A kind of rack and pinion steering gear of the utility model adopts such structure, the driver in driving procedure, steering wheel rotation, when being about near the steering lock position, hand-power can be felt to increase the weight of, and the driver is known reach the steering lock position; For commutator, change the rigid impact of tooth bar and housing into soft impulse, improve the working life of commutator; When turning to limit position, steering wheel can be automatically by the limit position one section very little stroke that rebounds, avoided steerig pump to be in the state of maximum service pressure, the working life of improving steerig pump.
